 Features and OptionsPower supplies are capable to "talk to each other," useful when a company" wants to input aircompressortahkcanada the same welding procedures into several machines at once or monitor the welding aircompressortahkcanada consistency and performance of several machines from a single location-through serial-data communications. Fabricators can take some of their machines aircompressortahkcanada and connect them to a personal computer to monitor performance, and download welding parameters to the machines from aircompressortahkcanada it memory card for fast setup. High-end machines will calculate the pounds of weld wire used per machine. The machine can also be prepped to constantly monitor and average the welding current and voltage used, so that fabricators can set limits on the machine and track how many times welding parameters fell in or out of these limits. Welding Torches and GunsUsed for shielded-metal-arc welding, torches (electrode holders). manually controlled, grip ends of electrodes, also called rods-pinch type and collet type are common.GMAW and FCAW guns come in pistol grip, goose-neck, and inline styles, the latter used for mechanized welding. Knowing the wire diameter, select a gun rated slightly higher than the welding current to be used. Duty-cycle ratings are usually given for C[O.sub.2] shielding--air or C[O.sub.2] cooling arc usually sufficient for welding at up to 600 A at less than 100 percent duty. Higher amperages require water cooling--high-amperage guns come with tubing for water cooling. Hand-held, mounted on a robot arm or fixed within a mechanized welding setup, guns guide filler wire and shielding gas into the weld puddle. Power SuppliesWelding power supplies take alternating or direct current from a power line or portable generator and convert it to current usable at the welding arc:, Check National Electrical aircompressortahkcanada Manufacturers Association (NEMA) Standards Publication EW1, Electric Arc Welding Power Supplies, and manufacturers'' literature for construction and performance requirements of individual machines.Among types of power supplies, alternating-current (ac) transformers are least costly-most use 230 V single phase input power. Direct-current (DC) transformer-rectifiers convert AC to DC, using single- or three-phase power to produce constant voltage (cv) or variable voltage (vv). AC-DC transformer-rectifiers can AC and DC weld. Searching for accessories for your air compressor? We offer the best selection of cheap air compressor accessories on the internet.
